There is growing evidence that tCBT has beneficial effects on both depression and anxiety in working-age people. However, the potential benefits of this approach have not yet been examined in older people (in whom psychological comorbidity is a frequent problem). Therefore, this study will aim to recruit 22 older people who are experiencing symptoms of depression and anxiety from community mental health teams within the South London and Maudsley National Health Service Trust. Participants will be randomly allocated to receive either tCBT plus treatment-as-usual (TAU) or 7-week delayed tCBT plus TAU. tCBT will be delivered on an individual basis in 12 sessions, each lasting 1 hour, over 14 weeks. It will be delivered in outpatient clinics or within the participants residence, depending on mobility issues. A number of outcome measures will be used to evaluate the feasibility, acceptability and efficacy of tCBT, including ratings on mood questionnaires, rates of dropout and reasons for dropout. Outcome measures will be collected before the tCBT intervention starts (week 0/baseline), midway through the intervention (after the 6th tCBT session/week 7), at the end of the intervention (after the final tCBT session/week 14) and at 7-week follow-up (week 21) .
